Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security system for ensuring safety when there is a vehicle running backward on a one-way street.

[0002]

2. Description of the Related Art When there is a vehicle that exits from a one-way road, an oncoming vehicle that sees this one will intentionally enter the one-way road in the opposite direction and travel (hereinafter referred to as "reverse travel"). It is not likely to end up, but when traffic is light,
There is a vehicle that runs backwards due to misunderstanding (hereinafter referred to as a reverse running vehicle). Especially on a highway, if you run backwards on the one-way road that connects the main line to the parking area and service area, the vehicle may run backwards on the main line as it is, so the driver of the reverse-running vehicle is in an early stage. It is desirable to be aware of the reverse run.

In order to prevent such reverse running, conventionally, a sign plate for prohibiting entry is placed beside the exit of a one-way road, a method for drawing a sign for prohibiting entry is drawn on the road surface, and the size of these signs is larger than usual. The method is adopted.

[0004]

However, particularly at night or in rainy weather, it is easy to overlook signs, and it is not always possible to prevent reverse running due to misunderstandings and driver's thoughts.

Therefore, for example, Japanese Patent Laid-Open No. 5-296775.
The gazette discloses a configuration for alerting a driver when a vehicle is traveling in a reverse direction on a traffic road. This technology refers to the map data stored in the in-vehicle navigator to generate a route from the departure point to the destination, compares the position information indicated by the vehicle position detection means with the guidance route, and determines that the vehicle is running backwards. It gives a warning of a reverse run when it is called.

However, the method using the in-vehicle navigator is not effective in a vehicle not equipped with the in-vehicle navigator or in a vehicle in which the in-vehicle navigator is installed but is not operated.
Due to the limit of the position detection accuracy of the vehicle-mounted navigator or the position error that usually exists, the driver may neglect the warning given by the vehicle-mounted navigator, or may ignore it due to presumption. Therefore, it can be said that the warning given by the in-vehicle navigator is weak in action, and it is more desirable that the driver is further instructed. Also,
A driver of a vehicle (hereinafter, referred to as a forward running vehicle) traveling in a forward direction on a one-way path (hereinafter, referred to as a forward running vehicle) does not take any precaution against a reverse running vehicle, so a reverse running vehicle appears. In some cases, it takes time to avoid the operation.

The present invention has been made in view of the above problems, and provides a means for increasing the restraining force against reverse running, and further, in the case where a reverse running vehicle exists, a driver of a forward running vehicle can afford it. It is an object of the present invention to provide means for avoiding this.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, the security system of the present embodiment is configured to include a reverse running notification device 1 as a reverse running reporting means, an exit side traffic light 4 as a forced prohibiting means, and an entrance side traffic light 5 as a forward running prohibiting means. ing.

The reverse running notification device 1, the exit-side traffic light 4, and the entrance-side traffic light 5 are all running lanes 50, which are the main lanes of highways.
Is installed on the side of the road along the one-way road 55 from the parking area 52 to the parking area 52. On the other hand, the one-way road 55 consists of one lane, and it is assumed that a forward running vehicle and a reverse running vehicle cannot pass each other. The exit-side traffic signal 4 is installed near the exit of the one-way path 55 so that a driver of a vehicle attempting to enter from the exit side of the one-way path 55 can visually recognize it. The reverse running notification device 1 is installed on the entrance side of the one-way road 55 by a predetermined distance from the exit side traffic light 4. The entrance-side traffic signal 5 is installed on the front side (outer side) by a predetermined distance with respect to the entrance of the one-way passage 55 so that the forward traveling vehicle that sees it can appropriately evacuate to the evacuation area 51a or the like.

The reverse running notification device 1 is composed of a vehicle detector 2 and a reverse running judging device 3 (see FIG. 2). The vehicle detector 2 is composed of a well-known electromagnetic wave type pulse radar type radar sensor with a distance measuring function, and measures the distance to the vehicle from the time difference between the transmission time of the radar wave and the reception time of the reflected wave from the vehicle. The vehicle detector 2 has an outside area A1 set inside the parking area 52 which is outside the exit of the one-way road 55.
And the inside area A2 set in the one-way passage 55 on the entrance side of the exit side traffic signal 4 are constantly monitored as detection areas, and the detection signal SD is output.

The reverse running determination device 3 is, for example, a CPU / RAM /
It consists of a well-known one-chip microprocessor equipped with a ROM and an input / output interface, detects and determines the position and running direction of the vehicle from the distance to the vehicle and its changes, and reports the approach to the exit of the one-way road. S
A and a reverse running report SR indicating the determination of a reverse running vehicle are output.

The exit-side traffic light 4 is equipped with three lamps 4a, which are red, yellow, and blue lights, and a receiving circuit, a determination circuit, and a display output circuit, like the well-known three-color traffic light. It is configured so that three types of operation states can be selected: traffic prohibition), yellow light lighting (caution), and blue light lighting (passing permission). The exit side traffic light 4 is normally set so that all the lamps 4a are turned off and the red light is turned on when the approach notification SA from the reverse running notification device 1 is input.

Similarly, the traffic light 5 on the entrance side is also a well-known three-color traffic light, and is provided with three lamps 5a of red light, yellow light, and blue light, a receiving circuit, a judgment circuit, and a display output circuit, and lights up the red light. It is configured so that three types of operating states can be selected: (passage prohibited), yellow light lighting (caution), and blue light lighting (passing permission).
The entrance side traffic light 5 is normally set to turn on the blue light and turn off the blue light and turn on the red light when the reverse running notification SR from the reverse running notification device 1 is input.

In the above structure, when the vehicle enters the outside area A1 from the center side of the parking area 52, the reverse travel notification device 1 outputs an approach notification SA, and in response to this, the exit side traffic signal. The red light of 4 lights up. The traffic signal forcibly prohibits the reverse running of the vehicle by lighting the red light based on the law, so the operating state when the red light is lit is:
It exerts a strong restraining effect on the driver of the vehicle trying to run in reverse.

When the vehicle enters the inner area A2, the reverse travel notification device 1 outputs the reverse travel notification SA, and the red light of the entrance side traffic light 5 is turned on accordingly. As a result, the driver of the forward-traveling vehicle attempting to enter the one-way road 55 from the traveling lane 50 can know the existence of the reverse traveling vehicle.

As described above, in this embodiment, since the exit side traffic light 4 is provided as the compulsory prohibition means for compulsorily prohibiting the reverse running, a high effect of suppressing the reverse running can be obtained.

Further, in this embodiment, since the exit side traffic light 4 is installed on the ground, it is possible to suppress the reverse running of a vehicle which is not equipped with the on-vehicle navigation, and the prohibition state (the red light is turned on) and the non-prohibition state. Status (yellow light / blue light)
Since it is configured to be selectable between and, it is possible to call the attention of the driver of the reverse running vehicle by the change of both states.

Further, in this embodiment, the exit side traffic light 4 is
Since it is decided to operate on the basis of the reverse travel notification (approach notification SA) from the reverse travel notification device 1 in which the outer area A1 on the exit side of the one-way road 55 is the detection area for the exit side traffic light 4, it is prohibited. The change between the state (red light is lit) and the non-inhibited state (yellow light / blue light is lit) can alert the driver of the reverse vehicle.

Further, in this embodiment, the driver of the forward traveling vehicle can recognize the presence of the reverse traveling vehicle by the entrance side traffic light 5, and
The entrance side traffic light 5 is the reverse running notification device 1 and the exit side traffic light 4
On the other hand, since it is installed on the entrance side of the one-way road 55, the driver of the forward running vehicle can avoid the reverse running vehicle with a margin.

Further, in this embodiment, since the entrance side traffic light 5 is configured to be selectable between the prohibited state (red light is lit) and the non-inhibited state (blue light is lit), it is possible to proceed according to a change between the two states. It can alert the driver of the car.

In the first embodiment, the prohibition is not compulsory by turning off all the lights on the exit side traffic light 4 at all times, and the red light is turned on only when there is a vehicle trying to run in reverse. Instead of such a configuration, instead of such a configuration, for example, the yellow light is normally lit and the red light is lit (yellow light is extinguished) only when there is a vehicle trying to run in reverse. Alternatively, the red light may be blinked at all times and the red light may be turned on only when there is a vehicle attempting to run backward.

Further, in the first embodiment, the exit side traffic signal 4
The red light of the exit side traffic light 4 is always effective because the red light of the exit side traffic light 4 is effective only for the long life of the lighting equipment of the exit side traffic light 4. You may set it so that it lights up. Even with such a configuration, unlike the case of a control means such as a sign that does not change the state, the prohibition state (red light) is selected instead of the non-prohibition state (blue light or yellow light). It can give the impression that it is being performed to the driver of the reverse-running vehicle, and can well draw the attention. In the case where the red light is always turned on as described above and the entrance side traffic light 5 is not provided, it is not necessary to detect the reverse running vehicle itself, and therefore it is not necessary to provide the reverse running notification device 1. .

In the first embodiment, the electromagnetic wave type pulse radar type radar sensor with a distance measuring function is used as the vehicle detector 2. However, instead of such a configuration, the vehicle detector 2 is an optical pulse type. A radar type radar sensor may be used. Alternatively, a radar sensor utilizing the Doppler effect may be used as the vehicle detector 2 to detect the modulation of the frequency of the received radar wave in accordance with the traveling direction and speed of the vehicle. The device 3 can determine the traveling direction of the vehicle by detecting this modulation.

Further, as the vehicle detector 2, for example, a well-known ultrasonic sensor, loop coil sensor, optical sensor or the like can be used. In these cases, it is preferable to use two sensors 2a and 2b as shown in FIG.

For example, two sensors 2a and 2b are arranged at different positions along the longitudinal direction of the one-way road at a predetermined height from the road surface so as not to obstruct the passage of the vehicle. When the vehicle V travels in the direction A, FIG.
As indicated by the solid line in (b), the sensors 2a and 2b are turned on in this order, and conversely, when the vehicle V travels in the B direction,
It is turned on in the reverse order as shown by the broken line. In this way, since the output change timings of the sensors 2a and 2b are different depending on the traveling direction of the vehicle V, the reverse running determination unit 3 is configured to detect both sensors 2
The traveling direction of the vehicle can be determined from the timing of the output changes of a and 2b, and the determination that there is a reverse vehicle can be executed.

In terms of security, it is more desirable to provide a plurality of exit side traffic lights 4, and the same applies to the entrance side traffic light 5. For this reason, three lamps of a red light, a yellow light, and a blue light should be provided on the back side of the exit side traffic light 4 (the side visible from the vehicle running forward), and operate under the same conditions as the entrance side traffic light 5 described above. Is preferred. In addition, there are three red lights, yellow lights, and blue lights on the back side of the traffic light 5 on the entrance side (the side visible from the reverse vehicle).
It is preferable to provide two lamps and operate under the same conditions as the exit side traffic light 4.

Next, the second embodiment will be described. The second embodiment shown in FIG. 4 is a warning device 14 with a signal light,
The circuit breaker 15, the character display 16, and the forward running notification device 21 are installed.

Warning device 14 with signal light and breaker 15
Functions as a compulsory prohibition unit that compulsorily prohibits reverse running, a forward travel prohibition unit that compulsorily prohibits forward running, and an alarm unit that outputs an alarm to a forward running vehicle and a reverse running vehicle. The character display 16 functions as an alarm unit that outputs an alarm to a traveling vehicle. The forward running notification device 21 functions as an entrance-side detection unit that detects a forward running vehicle.

The alarm device 14 with a signal light has an alarm area on both the exit side and the entrance side with the breaker 15 in between, and a signal light provided with two red lights on each of the entrance side and the exit side and an alarm sound. And a resulting speaker. The alarm device 14 with a signal light is in an operating state (that is, a state in which two red lights of the signal light are alternately blinking and an alarm sound is generated from the speaker in response to receiving an operation instruction SM from the cutoff possibility determining device 25 described later. ) Is set.

The circuit breaker 15 is constructed and installed so that the vehicle on the one-way road 55 can be blocked by setting the blocking rod at the blocking position.
It is set to be in an operating state (that is, a cutoff state) in response to the reception of the operation instruction SM from the.

The character display 16 is a well-known electric display plate installed so that the driver of the forward vehicle can visually recognize it, and although it is normally turned off, it gives an alarm instruction from the cutoff possibility judgment device 25 described later. It is set to display a predetermined character message (for example, “Attention !! There is a reverse running car !!”) in response to the reception of the SP.

The forward running notification device 21 has the same structure as the reverse running notification device 1 in the first embodiment, and includes a vehicle detector 22 and a forward running judging device 23. Vehicle detector 2
2 has the entrance side area A3 on the entrance side of the one-way road 55 with respect to the breaker 15 as a detection area, and the forward-running vehicle has an entrance side area A3.
Is configured to output the forward running notification SF when the vehicle enters.

As shown in FIG. 5, the approach notification SA, the reverse running notification SR, and the forward running notification SF are input to the cutoff possibility determining device 25. The cutoff possibility determining device 25 is, for example, a CPU / RAM / R.
It consists of a well-known one-chip microprocessor equipped with an OM and an input / output interface, judges whether or not the blocking rod of the breaker 15 can be set to the blocking position, and gives an operation instruction to the alarm device 14 with a signal light and the breaker 15. SM,
And an alarm instruction SP for the character display 16 is output.

The operation of the second embodiment will be described. First, when the vehicle enters the outside area A1 from the center side of the parking area 52, the reverse travel notification device 1 outputs an approach notification SA, and the shutoff possibility judgment device 25 responds to this by the signal light warning device 14. The operation instruction SM is output, and the two red lights on the exit side surface of the alarm device 14 with the signal light blink alternately. The alternating blinking of the two red lights psychologically prohibits the reverse running of the vehicle and is forcibly prohibited based on the provisions of the law. Therefore, this operating state is for the driver of the vehicle trying to run in reverse. It exerts a strong suppressing effect.

Further, the vehicle is located in the inner area A of the one-way road 55.
In the case of invading No. 2, the reverse running notification S from the reverse running notification device 1
R is output, and in response to this, the interruption propriety determiner 25 outputs an operation instruction SM to the circuit breaker 15, an alarm sound is output from the speaker, and the interruption rod is in the interruption state. The shut-off state of the shut-off rod forcibly prohibits the vehicle from running backwards physically, psychologically, and in accordance with the regulations of the law. On the other hand, it exerts a strong suppressing effect. In addition, the warning sound output on the ground can make the driver notice that an abnormal situation has occurred, and can be a trigger to reconfirm the surrounding situation. The blocking rod is returned to the non-blocking position when the vehicle detector 2 again reports the absence of the reverse vehicle or under a predetermined cancellation condition such as a lapse of a predetermined time from the notification of the absence. .

Further, the interruption propriety determination unit 25 outputs an alarm instruction SP to the character display unit 16, and the predetermined character message is displayed on the character display unit 16 by this. The display content of the character display 16 (that is, the degree of alarm by the alarm means) is made different between when the blocking rod is in the blocking state and when it is in the non-blocking state. It is also possible to give an alarm by means of 16 that the blocking rod is in the blocking position. Further, when the vehicle is entering the outer area A1 from the center side of the parking area 52, the character display device 16 gives an alarm to that effect, so that the driver of the forward-running vehicle can prepare for avoidance with a margin.

Next, even when the reverse running vehicle is entering the inside area A2, if the blocking rod can damage the forward running vehicle, it must be avoided. For example, if the forward traveling vehicle is close to the breaker 15 and the blocking rod is set to the blocking position, the vehicle immediately before the forward traveling vehicle will be blocked, and the forward traveling vehicle cannot stop and collides. There is a risk that the vehicle may collide with a forward vehicle in the process of setting the blocking rod to the blocking position. In order to avoid this, in the present embodiment, the output of the forward running notification device 21 is used to limit the shutoff operation of the breaker 15 when the forward running vehicle approaches the breaker 15 within a predetermined distance. .
That is, even when the reverse running report SR is output from the reverse running reporting device 1, the forward running reporting device 21 outputs the forward running reporting SF.
If there is, the interruption propriety determination device 25 does not output the interruption instruction SM as an exception, and performs a process of keeping the interruption rod of the interruption device 15 in the non-interruption position.

As described above, in the second embodiment, the character display 16 as the alarm means allows the driver of the forward running vehicle to recognize the presence of the reverse running vehicle. Since the entrance side of the one-way road 55 is set as the alarm area for the vehicle detector 2 and the circuit breaker 15 of FIG. 1, the driver of the forward running vehicle can avoid the reverse running vehicle with a margin.

Further, in the present embodiment, the character display device 16, the alarm device 14 with a signal light, and the breaker 15 are configured to be selectable between the prohibited state and the non-prohibited state. It can alert the driver of the car.

Further, in the present embodiment, the vehicle detector 22 in which the entrance side of the one-way road 55 with respect to the breaker 15 is the detection area
Since the circuit breaker 15 operates based on the forward running notification SF output based on the signal from the vehicle, the state change of the forced prohibition means can be caused in synchronization with the entry of the forward running vehicle. The driver's attention can be well aroused.

By the way, in the second embodiment, the shutoff rod is set to the non-shutoff position in the normal case where there is no reverse running vehicle, and the shutoff rod is set to the shutoff position when the vehicle detector 2 detects the reverse running vehicle. However, the operation of the circuit breaker 15 may be configured such that the blocking rod is set to the blocking position regardless of the presence or absence of the reverse running vehicle, and the blocking rod is set to the non-blocking position only when the forward running vehicle passes through. . In this case, it is preferable to detect that the forward-running vehicle has passed the breaking point of the breaker 15 in order to return the blocking rod to the blocking position after the forward-running vehicle has passed. The output related to the internal area A2 of the running report device 1 may be used, or a dedicated sensing means may be newly provided.

In this way, when the feeling of interruption is always in the interception position, it is sufficient to keep the interception rod in the interception position with respect to the reverse running vehicle. To detect if a car has passed a blocking point,
It is preferable to set the internal area A2 as the second monitoring area of the forward running notification device 21.

On the other hand, when there is a reverse running vehicle, the blocking rod may be kept in the blocking position even when the forward running vehicle approaches the breaker 15. That is, normally, when the shut-off rod is set to the shut-off position and the forward running notification device 21 outputs the forward running notification SF,
As a general rule, the interruption propriety determiner 25 outputs the warning instruction SM to set the interruption rod to the non-interruption position, and as an exception processing, when the reverse travel notification SR is output from the reverse travel notification device 1, Despite the notification of the run report SF, the instruction to release the blocking rod may not be issued. At that time, it is desirable to warn the forward traveling vehicle that the blocking rod is at the blocking position, and the blocking availability determination device 25 issues a warning to that effect to the character display 16 by the warning instruction SP. It is preferable to give instructions accordingly.

As a result, since the shutoff rod is kept in the shutoff position, both the reverse running vehicle and the forward running vehicle can be safely stopped, and further, when the forward running notification SF occurs in the breaker 15. Since the non-prohibited state is selected and the prohibition state is selected when the forward running notification SF is not generated, the forward running vehicle is the detection range of the vehicle detector 22 of the forward running reporting device 21 on the entrance side. The alertness of the forward-running vehicle can be aroused until the vehicle enters the area A3. Further, even in the case of the circuit breaker 15 which is set to release the cutoff state by detecting the forward running vehicle, the shutoff state is continuously selected as the reverse running vehicle enters, and the attention of the driver of the forward running vehicle is reduced. Can be evoked.

Further, the shut-off rod is normally set at a position approximately midway between the shut-off position and the non-shut-off position (hereinafter referred to as an intermediate position). If there is any, it may be configured to be in the blocking position.
In that case, when there is the forward running notification SF, the blocking rod is set to the non-blocking position by the operation instruction SM (= 1). On the other hand, if there is a reverse running report SR, the cutoff possibility determination device 2
5 sets the blocking rod of the breaker 15 to the blocking position according to the operation instruction SM (= 0). According to this structure, it is possible to quickly move to each position regardless of whether the blocking rod is in the non-blocking position or the blocking position. Reverse run report SR is forward run report S
When the reverse running notification SR reports that there is a reverse running vehicle, the blocking rod is set to the blocking position regardless of the presence of the forward running reporting SF. At that time, the warning instruction S
By P, an alarm output is instructed to the character display 16. When neither the operation instruction SM nor the reverse running notification SR has been notified, the blocking rod is set to the intermediate position.

It may be necessary to cancel the reverse running prohibition operation or the forward running prohibition operation at the appropriate timing. In general, a reverse-run vehicle that has entered a one-way road continues to run in the opposite direction and exits from the entrance of the one-way road as it is, or turns back in the middle of the one-way road and exits from the exit of the one-way road. Either, or it will stay in the middle of the one-way road, but in the case of the former two of these, that is, when the reverse running car is no longer present on the one-way road, The reverse running prohibition operation or the forward running prohibition operation may be released as soon as the above can be confirmed.

Therefore, in addition to the configuration of each of the above-described embodiments, means (for example, equivalent to the vehicle detector 2 in the first embodiment) that can determine the traveling direction of the vehicle is provided near the entrance of the one-way road 55. A predetermined counter is provided to count the number of reverse running vehicles entering from the exit of the one-way road 55 one by one, and the counter is set to 1 when a reverse running vehicle is detected by a vehicle detector installed at the entrance. The forward running vehicle is detected by the vehicle detector provided at the exit (the forward running vehicle in this case has a narrow width of the one-way road 55 and a difference between the backward running vehicle and the forward running vehicle in the one-way path 55). If it is not possible, it is configured such that only 1 is subtracted when it is detected that the vehicle is the reverse vehicle that has entered from the exit first, and that the count value of this counter is zero (that is, the one-way road 55 There is no reverse vehicle The condition may be configured to release the prohibition operation of the forced prohibiting means such as outlet-side traffic 4.

The various means in each of the above-mentioned embodiments may be appropriately combined and used. For example, as the above-mentioned forced prohibition means or forward prohibition means, any one of a signal light, a breaker, and a pseudo light device may be used. 2 or more different types may be combined, and such a configuration also belongs to the scope of the present invention.
